The paging space may be increased on the fly using the ‘chps’ command. In order to increase this paging space to 2 GB we need to to find out the PP size, since chps will increase the paging space by the specified number of PP’s

Microcode Discovery Service in short MDS enables in conjunction with the invscout AIX tool to survey your system for the installed microcode levels on devices such as network adapters, HBA’s, HDD’s etc., and also the system (service procesor) microcode itself. The collected information from the invscout tool is exported to a file. This file can be uploaded to the MDS website which generates a simple report with an overview of the microcode levels of your devices and the current/latest microcode levels. Also for each device and his microcode level there is a coresponding readme file and a download link for the microcode.

In this post I will describe the microcode update procedure on a scsi adapter using the MDS and invscout.Read More

AIX offers tools that allow the administrator to change configration files without editing them directly, thus reducing the possibility of causing a service outage caused by a typo in the configuration file, as described in more detail here.

In this example I have a NFS client with a filesystem mounted from the server cosmos in order to change the mount options so that the filesystem is mounted with the options soft and bg (background) I use the following command instead of directly editing /etc/filesystems.

In this post I will describe a TL upgrade using multibos on AIX 6.1. The system will be moved from 6100-04 to 6100-07 (TL4 to TL7).

1. Create a separate filesystem for the updates 2. Create a backup of the system 3. Check current TL level 4. Preview/Create the multibos standby BOS instance. 5. Preview/Patch the OS in the standby instance 6. Verify the oslevel in the standby instance after the update 7. Reboot and check 8. Optionally return to the pre-update BOS image.Read More
